“It was major flooding — there was nothing that we could have done,” Alpha Project Chief Operating Officer Amy Gonyeau said. “The water was like 3 feet high in places. It was really crazy. I’ve never seen it like that.”

According to the National Weather Service, downtown San Diego received 2.27 inches of rain between 8 p.m. Tuesday and 8 p.m. Thursday.

The sudden onslaught of precipitation Thursday evening that prompted the flash flood warning overwhelmed low-lying areas throughout the county, including the tent shelter near Newton Avenue and 16th Street.

“It all happened so fast, it was crazy,” Gonyeau said. “But the staff is safe, the clients are safe, and the city was great.”

Gonyeau said city officials quickly sent several Metropolitan Transit System buses to transport the shelter’s clients to the stadium. Police radio traffic indicated the buses carrying the shelter evacuees traveled in a caravan to the stadium a little after 11 p.m. Flooding at the tent shelter had begun several hours before.

The Alpha Project tent and two others like it, which are operated by different organizations, shelter about 700 people total and opened near the beginning of the year. They were proposed as bridge shelters, meaning they were intended to be a bridge from the street to a home.

Along with the Alpha Project’s 324-bed tent, which is for homeless adults, Father Joe’s Villages operates a 150-bed tent downtown for families and single women, and Veterans Village of San Diego operates a 200-bed tent for veterans in the Midway District.

“Damages are yet to be determined,” Gonyeau said. “We have no idea when we’ll be able to reopen.”

Authorities said the scandal centered around the owner of a for-profit Newport Beach college admissions company that wealthy parents paid to help their children cheat on college entrance exams and to falsify athletic records of students to enable them to secure admission to elite schools.
